28.5Kwh per day!

[camillitech]

It's been over a month since 'Mr Lister' our back up genny fired up and he'll now do precious little work until March, well until we have a calm frosty spell that is  

My wind, hydro, diesel, battery system does not really have any easy way of monitoring the total power produced accurately. I do have meters on everything but the wind turbine, however the generator Kwh meter includes loads permanently connected and I often run it for welding or a diving compressor.

Anyway the boy came home from school on Friday with homework that included two days power consumption so I thought I measure what we'd produced as well as used over that period. I was very pleasantly surprised.

The Proven 2.5 and ES&D hydro turbine generated 57Kwh between them in a 48 hour period. The stream engine being the clear winner at 30Kwh  

We used 18Kwh in the house which is over double our 4.3Kwh per day average (taken over six years) but that was due to marathon baking and washing sessions. When you've got it you might as well use it   My chalet used 2Kwh but it was empty for one day and the dump loads (three oil filled radiators) in the house consumed a massive 37Kwh  

All I need now is some more PV

Good job.

There might be some cheap PV going after December 9th. Somebody's going to have to dump stock.

hey Paul

you are on your way for an electric Landi

As long as he can have a plug in point at the ferry terminal.

Be interesting to see how long the roof would stay on that one!

Richard Owen,

Please, please sir, i only require 3Kw, spare some PV for little me, i only have £3,000.

I'd wait until the axe falls and then start offering your £3k and see who bites.

All I need now is some more PV  

And some sun in the sky to power them...

Or have you been pushing all the cloud down this end of the Island?

October generation to the 30th stands at 84% of the PVGIS estimate for the month, with the average daily figure currently standing at 3.6kWh/day.  Looking out of the window, when I add today's data to that the figures will probably fall a little further. That's the lowest monthly %age we've seen so far (even May managed 90%).

However, last October was 140%, so swings & roundabouts...

I look forward to 'our turn' for a better than average May, June or July.

I want one Billi   though I think I'd skip the sun shade, didn't see any mention of range on there  

Pretty poor figures for October David, but as you say 'swings and roundabouts' seem to remember Mr Lister starting every other day for a while last December, usually one of the wettest and windiest months.

Richard, Clockman, definitely a time to sit and wait on the PV front I think, I see them going only one way  

Shhhh Billy  

Today was even better, 8kwh used in the house, 3kwh in the chalet and 20kwh dumped via the heaters and that was in 23 hours  

The 'Stream Engine' produced a pretty constant 810w, so around 19.4Kwh with the Proven making up the 11.6Kwh to produce the 31Kwh for the day.



Pretty poor really when you see how windy it's been, I'm thinking the old Proven is needing new blades   Mind you, I suppose that's after charging and inverter losses so perhaps not as bad as it looks. The figure for the hydro turbine is before the transformer so an unrealistic comparison really.

Cheers, Paul

Are your data feeds automatic or do you gather the data manually and input?

[camillitech]

Hi Clivejo,

my data comes from five meters, one on each of the supplies to my house and chalet, one from the AC output of the genny. One on the AC output of the hydro turbine and one of the AC supply to the dump loads.

It's not totally accurate because the hydro turbine meter is before transformer, battery and inverter losses and the DC dumps that come in at 60v are not monitored (and they've been getting plenty of use of late  ) I'd love to know what we've produced over the last week as the hydro turbine has been doing 800w continuously for weeks now and the Proven has been belting out 2.4Kw for hours on end in the recent force 11's

Cheers, Paul

I'd worry more about the inside temps 24/25c -do you all walk round in your pants?

What I mean is do you read the meters and enter the data manually or is it electronically gathered in logs and transmitted via a computer network?

[camillitech]

And that's with the windows open George  Down side is once the high pressure and frost arrive it's boodly  in here.

Morning Clivejo,

"What I mean is do you read the meters and enter the data manually or is it electronically gathered in logs and transmitted via a computer network? "

all done manually then entered in a notebook (sometimes  ) though the weather data and graphs are done automatically via a wireless link to the sensors and a USB cable on the station. That's exactly two years it's been up and it's still on the same batteries

Cheers, Paul
